Troubleshooting the Server 27
2. Disconnect the AC power cables from the server, extend the server to the
maintenance position, and remove the server top cover.
See “Preparing the Server for Component Replacement” on page 33 .
3. Inspect the internal status indicators (LEDs), which can indicate component
malfunction.
For the LED locations and descriptions of their behavior, see “Motherboard Status
Indicators” on page 13 .
To light these LEDs, press and hold down the Fault Remind button, which is
located on the motherboard. For more information on the Fault Remind button,
see
“Using the Fault Remind Button” on page 70 .
4. Verify that there are no loose or improperly seated components.
5. Verify that all cables inside the system are firmly and correctly attached to their
appropriate connectors.
6. Verify that any components that you ordered separately and were not installed
at the factory are qualified and supported.
Check with your customer representative for information about which PCIe cards
and DIMMs are supported.
7. Check that the installed DIMMs comply with the supported DIMM population
rules and configurations.
For more information, see “DIMM Population Rules” on page 67 .
8. Return the server to operation.
See “Returning the Server to Operation” on page 143 .
9. Press and release the Power button on the server front panel.
When the main power is applied to the server, the Power/OK indicator next to the
Power button blinks slowly until the OS is ready. When the OS is ready, the
Power/OK indicator remains lit. For more information about the indicator, see
“Server General Status Indicators” on page 7 .
10. If the problem with the server is not evident, then log in to either the Oracle
ILOM Fault Management Shell or Oracle Solaris service portal and use the fault
management command
fmadm faulty
to list any faults that might be present
on the server.
